This European Standard describes a method for the determination of the total Cadmium (Cd) content in plastics in the range of 10 mg Cd/kg to 3 000 mg Cd/kg. It is not suitable for polyfluorinated plastic materials.
Wet decomposition of organic compounds and dissolution of cadmium compounds in a sample involves the atomization of a solution in the flame of an atomic absorption spectrophotometer and the measurement of the absorbance at a wavelength of 228.8 nm.
Requirements for the reagents, apparatus, repeatability and reproducibility are given as part of this test method.
